Efficient enriching high-performance denitrifiers using bio-cathode of microbial fuel cells.

ABSTRACT: Recent advancements in microbial fuel cells (MFC) technology have significantly contributed to the development of bio-cathode denitrification as a promising method for eco-friendly wastewater treatment. This study utilized an efficient repeated replacement method to enrich a mixed bio-cathode denitrifying culture (MBD) within a bio-cathode MFC, achieving a stable maximum output voltage of 120 ± 5 mV and a NO₃ ^--N removal efficiency of 69.99 ± 0.60%. The electrotrophic denitrification process appears to be facilitated by electron shuttles. Microbial community analysis revealed a predominance of Proteobacteria, with Paracoccus and Pseudomonas as functional genera. Additionally, the isolated strain Lyy (belonging to Stutzerimonas) from MBD dem
